Multinomial test in Python with met module

Question

I am trying to conduct a multinomial test in Python --the analogous in R would be:

library(XNomial)
xmulti(prfs, c(1/3, 1/3, 1/3), statName="Prob")

I am using the met module. However I get an exception. Here is the code:

prfs
    Pref
A   8
B   21
C   31

import met
met.twosided_exact_likelihood(ref_obs = [1/3, 1/3, 1/3], site_obs = prfs.Pref/prfs.Pref.sum())

AttributeError: module 'met' has no attribute 'twosided_exact_likelihood'

Answer 1

This late reply may be moot, but somebody just notified me of this question. I'm the author of the met module. Evidently the latest version was lost from PyPI at some point, perhaps during the transition to the new warehouse. I have just re-uploaded the latest code and a little additional documentation.
